A thermodynamic criterion for selection of a fluid both for subcritical and supercritical organic Rankine cycle has been proposed. Theoretical performances of few fluids have been comparatively assessed for use in low-temperature domestic organic Rankine cycle micro systems. Of 20 fluids investigated, ethanol, R123 and R141b appear as the most suitable for small scale domestic CHP applications.
